The manufacturing process of silicon carbide (SiC) powder involves several critical stages that ensure the final product meets the required specifications for various industrial applications. Here’s a breakdown of these stages:
Material Preparation
The first step involves sourcing high-purity raw materials, typically silica (SiO2) and carbon (C). These materials are carefully selected to minimize impurities, which can adversely affect the properties of the final silicon carbide product. The raw materials are then blended in precise ratios and subjected to milling to achieve a consistent particle size.
Forming
In this stage, the prepared raw materials undergo a carbothermal reduction process. The mixture is placed in a furnace where it is heated to high temperatures (around 2000°C) in an inert atmosphere. This process facilitates the reaction between silica and carbon, resulting in the formation of silicon carbide. The method employed—whether it’s traditional Acheson or more modern methods—can significantly influence the quality and morphology of the SiC powder.
Finishing
After the initial formation, the silicon carbide is cooled and then subjected to further processing. This may include additional milling to achieve the desired particle size distribution and surface morphology. The powder is often classified to ensure uniformity in particle size, which is crucial for applications such as abrasives and semiconductor substrates.
Quality Control (QC)
Quality control is integral to the manufacturing process. It includes regular testing at various stages to ensure the product meets international standards and customer specifications. Key techniques include particle size analysis, surface area measurement, and chemical composition analysis.
